Where do they think the information on real time traffic speeds for various commuter routes comes from?
People also complain about governments not addressing congestion issues at certain locations, this sort of data, along with average speeds is how municipalities make determinations on what sort of road construction to do
"The sat-navs in TomTom's Live range all feature built-in 3G data cards, which feed location and route information back to a central server, which allows TomTom to create a map of congestion hotspots. It's now emerged that this data, however, along with a user's speed, is being made available to local governments and authorities."
